Factors affecting the delivery of an intervention into another site:
(1) feasability
(2) adequate coverage (available to enough people)
(3) acceptability of the interventions to the recipients
(4) effectiveness
Feasability includes:
(1) capability of healthcare providers
(2) availability of necessary resources and infrastructure
(3) cost
(4) compliance with political or cultural restrictions
(5) acceptance by decision makers and providers
(6) barriers
Adequate coverage involves delivery of the intervention:
(1) to all sites
(2) to all population subgroups
Acceptability to recipients:
(1) meeting a need (something they want)
(2) side effects
(3) compatibility with cultural and social norms
(4) costs in time. money and bother
The effectiveness of the intervention should be determined in different groups to find out who benefits from its use. An intervention may not work the same at a new site if the new population differs from the original study participants.
